Hello! Thanks a lot for your feedback and interest!
We are a team of blockchain enthusiasts specialized in IT, FinTech, blockchain, security, marketing, design and UI/UX.
Recently we have made our Zcash SPV library open-sourced, you may catch up with it on our GitHub: https://github.com/guardaco/zcash-SPV.
We do not have fully open-sourced projects as we would like our code to stay intellectual property of the company. However, if the community wants to audit our code we are open for any closed circuit code review. In future, we’re going to make our apps partly open-sourced like Jaxx or other light wallets did.
Nice website/wallet interface, but i think making your wallet is open-source would be better since some people including me have hard time trust wallet which is closed source and if i'm right there are license and intellectual property protection for open-source project
Also, AFAIK there aren't many mobile cryptocurrency wallet which are decentralized, open-source and user-friendly yet.
The've just made an open sourse and added a chrome extension, which is pretty nice
